On the Practical Security of a Leakage Resilient Masking Scheme
At TCC 2012, Dziembowski and Faust show how to construct leakage resilient circuits using secret sharing based on the inner product [2]. At Asiacrypt 2012, Ballash et al. turned the latter construction into an efficient masking scheme and they apply it to protect an implementation of AES against side-channel attacks [1]. The so-called Inner-Product masking (IP masking for short) was claimed to ...
متن کاملTheory and Practice of a Leakage Resilient Masking Scheme
A recent trend in cryptography is to formally prove the leakage resilience of cryptographic implementations – that is, one formally shows that a scheme remains provably secure even in the presence of side channel leakage. Although many of the proposed schemes are secure in a surprisingly strong model, most of them are unfortunately rather inefficient and come without practical security evaluati...
متن کاملOn hardening leakage resilience of random extractors for instantiations of leakage-resilient cryptographic primitives
Random extractors are proven to be important building blocks in constructing leakage resilient cryptographic primitives. Nevertheless, recent efforts showed that they are likely more leaky than other elementary components (e.g. block ciphers) in unprotected implementations of these primitives, in the context of side-channel attacks. In this context, from the adversary’s point of view, the extra...
متن کاملLeakage Resilient One-Way Functions: The Auxiliary-Input Setting
Most cryptographic schemes are designed in a model where perfect secrecy of the secret key is assumed. In most physical implementations, however, some form of information leakage is inherent and unavoidable. To deal with this, a flurry of works showed how to construct basic cryptographic primitives that are resilient to various forms of leakage. Dodis et al. (FOCS ’10) formalized and constructe...
متن کاملLeakage-Resilient Tweakable Encryption from One-Way Functions
In this paper, we initiate the study of leakage-resilient tweakable encryption schemes in the relative key-leakage model, where the adversary can obtain (arbitrary) partial information about the secret key. We also focus on the minimal and generic assumptions needed to construct such a primitive. Interestingly, we show provably secure constructions of leakage-resilient (LR) tweakable encryption...
